Figure 'l is a horizontal sectional view taken on the lines 'll-'i of Figure 6, and

Figure 8 is a horizontal sectional view taken on the lines 8 8 of Figure 2, and shown on an enlarged scale.

Referring more particularly to the drawings wherein like reference characters designate likey or corresponding parts throughout thediierent views, l0 designates generally the stove, il a con- (oi. ias- 25) ventional tent, as seen in `dotted lines, and i2 the earths surface or ground level.

The st ve designated, generally ld, includes casing preferably formed of sheet metal, and

he top i3, end walls lll and l5, bot- 5 'i5 and il', lrear wall i3 and front se portions are preferably conoi the joints 2@ which are prefof the portions 2i which are l -k u on themselves to clarnp the anges 10 y otrH i suitable form of joint may be ci tuted for the joint 2d if desired` n extends upwardly from between sections i3 il, and extends the .stove iii with its opposite ends 24 15' through tlc slots W5 formed, by the l ctions of t e end walls l5 and l outwardly upon theinlseves as ""cure 8. Clamps 2l which are le inturned longitudinal edges to 20 tion removably retain the secends and i5 in clamping engagef angular shaped ends Ell of partibottoni edge of partition 23 pro- 1ly between the downturned flanges 25 1 secu -ns l@ and ll', and is proviccd with the t iid which are bent outwardly upwardly, alternately in opposite directions to c tmp the bottoni of the partition 23 to the adjacent edges of the sections lil and il, as 30 best seen in Figures 2 and ll. Partition 23 adjacent its upper end, is bent rearwardly along the line Sd and the portion Si of partition 23 above the line 35i converges sharply to a point at 32 where it contacts the joint 2li of the back i8 and 35 top i3 oi the stove it?, to form the inwardly converging corresponding openings 33 between the iront compartment and rear compartment 35 of the stove, which are formed by partition 23.

End sections i5 of the compartments 34 and 40 35 are provided with the openings 3d and 3l respectively, the opening 35, which is the larger of the two, being closed by a door 38,'and the opening being closed by the dcorv. Doors 38 are each formed of the inner and outer spaced 45 walls vlil and li respectively forming the air chambers i2 therebetween to provide heat insuiating means to'keep the outeriwalls 4l relatively cool when the stove l@ is in use. Door 38 is provided with the openings @i3 in its outer wall 50 di through which air may circulate through its cooling space As best seen in Figure 1, door 33 is vertically hinged at @l and while the door 39 is horizontally hinged at its top at iisd thatthe' weightof the door 39 will normally re- 55 tain it in a closed position. Door 38 on the other hand, is provided with a pivoted latch 46 having a handle 41 and adapted to engage a stationary keeper 48 on the end wall I5 to retain it in a closed position.

A sheet metal plate 49 having the two downturned sides and the downturned back end 50, is positioned horizontally in compartment 34 adjacent its bottom I6 and is held therein by the brackets 5I, which comprise strips of metal extending the length of the partition 23, and the front I9 and the width of the front section of the end wall I4, and which are secured along their lower edges by suitable fastening means, and have their upper edges 52 offset inwardly to receive the downturned flanges 50 to removably retain plate 49 therein. Plate 49 substantially divides compartment 34 to form the fire box in the upper part of said compartment, and the ash pit beneath plate 49. As best seen in Figures 2 and 5, plate 49 is provided with a plurality of transverse spaced slits the opposite edges of which are bent downwardly to form the slots 53, thereby forming the inverted U-shaped bars 54 between the slots 53 to convert the plate 49 into a removable grate. Front wall I9 as best seen in Figure 6, is provided with a plurality of spaced openings 55 which communicate with the ash pit beneath the grate 49, and the bracket 5I which is secured to wall I9 is provided with an offset lower edge 56 corresponding to the upper offset portion 52 to cooperate with a bracket 51 corresponding to the brackets 5I to form a guideway for a plate 58 which is slidably mounted on the inner side of wall I9. Plate 58 is provided with a plurality of spaced openings 59 which are adapted to align with openings 55, and with a handle 60 which projects outwardly through one of the openings 55 and by means of which plate 58 may be moved relatively to the wall I9 to close or partially close the openings 55. It will thus be seen that an adjustable up-draft is provided whereby air may be admitted from without into the bottom of compartment 34 to pass upwardly through the slots 53 to provide a draft for the fire in the upper part of compartment 34.

Stove II) at its four bottom corners is provided with the removable legs 6I formed of angle iron, which are suitably secured to the bottom corners of the stove by any suitable means not shown, to elevate the stove from the ground I2.

As heretofore mentioned, and as best illustrated in Figure 1, the stove I is constructed as a portable campers stove and is particularly adapted for use in tents. As seen in Figure 3, bottom section I1 of compartment 35 is provided with an opening 62 into which is tted an end 63 of a stove pipe, designated generally 64, which has an intermediate portion 65 positioned below the earths surface I2 and an upwardly extending opposite end 66 through which the smoke and other products of combustion from the stove I0 is expelled. Intermediate portion 64 which is disposed beneath the ground and which extends away from the stove I0, permits the end 66 to extend upwardly on the outside of the tent l I, as best seen in Figure l, so that no opening need be made in tent II to accommodate thepipe 64. Pipe 64 comprises a plurality of pipe sections 61 and the two elbows 68 which are adapted to be disassembled for transportation, and stored in compartments 34 and 35 together with the legs 6I thereby forming a compact assembly for transportation.

From the foregoing it will be seen, that the door 38 may be opened to build a fire on the top of the grate 49 and for the purpose of feeding the re and removing the ashes from the bottom of compartment 34, and the draft for the fire may be controlled by adjusting the draft plate 58. Air will be drawn in through openings 55 and 59, upwardly through slots 53 to convey the heat and products of combustion from the fire not shown, upwardly through openings 33 into compartment 35, downwardly through end 63, through the subterranean portion 65 and upwardly through end 66 to be expelled beyond the tent Il. The entire top I3 of the stove I0 is adapted to be used for cooking, and the converging portion 3| directs the heat as well as the products of combustion toward the opposite ends of top I3 so that substantially the entire top sur face of the stove will be subjected to a uniform heat. Pipe sections 61, elbows 68 and legs 6I are inserted through the openings 36 and 31 in the section of the end wall I for storage and transportation.

Various modications and changes in the construction and arrangement of the parts forming the invention may obviously be made and are contemplated, as the drawings and description are only intended to illustrate a preferred form of the invention, and the right is reserved to make such Variations and changes as do not depart from the spirit and scope of the invention as hereinafter dened by the appended claims.
